logd: gtest: logd.timeout socket does not clean up properly

Until the socket ages out, it sticks around and gets reused in
subsequent tests affecting the outcome of those tests.  We opt
to run logd.timeout in a forked and isolated process to keep
these conditions from interfering.

Adjusted benchmark execute to only run the tests we are
interested in to improve the time it takes to run.

Commented some areas of code to make them easier to maintain.
